Greetings from South Devon! I'm new to BackdropCMS (from the D7 world) and am trying to create a subtheme of Bootstrap_lite. So far, so good. However, Instead of the 25% - 50% - 25% column layout for two sidebars and main content, I want to alter to something like 20% - 60% - 20%.
I'm new to Bootstrap also and could do with a pointer to where I would make this change most effectively. Is it Bootstrap? Is it Layouts?
I'm learning on the fly so anyone with wise words would be most welcomed!
